Compatibility

[Stephbeee]

We have a super old thermostat for our heat only system - no labels only two wires, one black, one white. Is this compatible with any of the Nest thermostats? Do we need to add a power adaptor? 

Thanks for your help!

Hello @Stephbeee 

Thanks for reaching out to our Nest community about this new installation. I'm so sorry for all the inconvenience. Don't worry, I'm here to help you with it.

To make sure about the answer for your compatibility could you share with me more details about your HVAC system for example if you have a Heat Pump or is a Convectional and what is the fuel source (gas, electric, oil, propane (LP) or geothermal).                      With these details i can confirm the compatibility with your system.

Feel free to keep us posting, I'm here to help you.

Kind regards,

Douglas.
